Nike is introducing the ACG Zegama: a rugged, athlete-tested silhouette that combines premium cushioning, protection, and traction to help runners move across the world’s wildest terrain — all day and all night.
Built for ultramarathons and long days in the mountains, the ACG Zegama is the most rugged model in the All Conditions running footwear lineup. The sneaker offers runners a cushioned ride that leaves no distance or terrain off limits.
The latest evolution in the trusted Zegama lineage of trail running footwear positions exposed ZoomX foam directly below the foot, delivering a comfortable ride and 85 percent energy return. ZoomX, Nike’s lightest and most responsive midsole compound, also pairs with a bed of Cushlon 3.0 foam to offer runners an added sense of stability on uneven trails.
A Vibram Megagrip outsole, with an improved lug pattern and strategic rubber coverage, provides unparalleled traction in both dry and wet conditions. It delivers long-lasting durability, meeting the rigors of every run head-on. Additionally, a forefoot rock plate helps runners move across rocky trails, and a modified heel bump improves foot placement in technical terrain.
Elsewhere, a new trail-specific last provides a more accommodating fit by adding room in the forefoot and toe box. A stretchier, more adaptive gaiter helps keep out rocks and other trail debris. Finally, padding in the tongue and heel offer more comfort over long distances, and a fit band drives additional midfoot support and consistent lockdown.
Every aspect of the ACG Zegama was informed by feedback from the All Conditions Racing Department: 22 elite trail athletes from eight countries and five U.S. states who have put the silhouette through its paces in race-like environments around the world, covering 50 to 100 miles at a time. Many athletes tested the ACG Zegama for up to eight weeks, logging upward of 400 miles. Their feedback, combined with dynamic Nike ACG wear testing during development, helped designers fine-tune the silhouette to the exact demands of ultramarathons and the audacious athletes who run them.
The ACG Zegama draws on Nike ACG’s legacy of creating light footwear that is fast and speaks to trails fluently — delivering bold solutions matched only by the tenacity of the athlete who chooses wild.
The Nike ACG Zegama will be available in summer 2026 at nike.com and select retail partners.
